Official image of the upcoming Sony Xperia Z (Yuga) leaks

2012 is gone and Sony is gearing up to announce its flagship Android phones for the new year. Two official images managed to slip through the cracks before the January 7 press conference, those of the Sony Xperia Z and the Xperia Odin.

Both images are hosted on SonyMobile.com and in the case of the Xperia Z, the image filename confirms the name (the phone used to be known by its ‘Yuga’ codename).

The Sony Xperia Z will enter the arena with other phones with 5” 1080p screens this year but it also puts Sony into the quad-core race with its Qualcomm APQ8064 Snapdragon S4 Pro chipset. The Z will come out with Android 4.1 Jelly Bean at launch.

The Xperia Z packs a 12MP camera, which reportedly performs better than the 13MP shooter on the Xperia T. There's a dedicated shutter key.

We found out a lot more details about it from the early preview of a pre-production unit.
